CUSHION-TIRE WHEEL.

Specification of Letters Patent.

Patented Dec. 2'?, 1910.

Application filed February 2, 1910. Serial No. 541,442.

To all whom it may concern:

Be it known that I, CHARLES A. MARIEN, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulCushion Tire Wheel, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to a cushion tire wheel and particularly to acushion tire wheel in which the tire is composed of a number of sectionswhich may be separately secured to and removed from the wheel.

One object of my invention is to so construct the tire that it willobviate the jar which takes place in the ordinary sectional tire whenthe point of contact between the tire and ground passes from one sectionto another.

Another object of my invention is to provide improved means for securingthe sections to the periphery of the wheel.

In the accompanying drawings which illustrate one form of wheel made inaccordance with my invention Figure 1 is a top plan view of a portion ofthe wheel; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 8 is aview showing a detail of construction and Fig. 4 is a section on theline 4-4 of Fig. 2.

Like marks of reference refer to similar parts in the several views ofthe drawings.

10 represents the felly of the wheel which is preferably made of woodand which may be of any usual form. Surrounding the felly 10 is a rim 11preferably having its sides 12 turned over as best shown in Fig. 2, soas to form a. channel for the reception of the tire proper. The sides ofthe rim 11 project bcyond the felly 10 as shown in Figs. 2 and 3.Situated in the channel formed by the rim 11 is the tire which consistsof a numberv of sections formed of rubber or other resilient material.These sections each consists of a body 13 and a base 14. The base 14 isof such width as to fit snugly within the rim 11. The bodies 13 aresomewhat shorter than the bases so as to leave spaces 15 between theadjacent ends of the bodies to allow for the iow of the material of thetire when the tire is compressed. The ends of the sections are inclined,as best shown in Fig. 1 so that as the tire passes over the ground onesection will come into contact with the ground before the other .haspassed out of contact therewith. v

In Fig. 1 A represents the line at righi angles to the plane of thewheel and will coincide with the line of contact of the wheel with theground. It will be evident from this View that one section of the wheelwill come into Contact with the ground before the other has passed outof contact therewith. Placed between the ends of each pair of sectionsis a cross-bar 16. Each of these bars 16 is provided with a pair ofpockets 17 one at each side of the bar. These pockets 17 are adapted toreceive the ends of rods 18 passing longitudinally through the sectionsand also to receive projections 19 formed of the ends of the bases 14 ofthe sections. These pockets 17 are made of slightly less depth than theprojections 19 as is shown in Fig. 3 so that the said projections willbe compressed when the bars are drawn down into position. The bars areheld in position by means of bolts 20 passing through the cross bar 16and the extending portion of the rim 11 and engaging with nuts 21.

By the use of my form of tire the olting usually caused by sectionaltires is obviated without resorting to the twin or double type of tire,at the same time the construction is extremely simple and the sectionswhile readily removable separately are very rigidly held so that theliability of tearing the reinforcing. rods loose from the resilientmaterial of the tire is overcome.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent of the United States is:

The combination with a wheel, of a channel-shaped rim on said wheel, atire of resilient material formed in sections` the ends of said sectionsbeing inclined to the plane of the wheel, the base of each of saidsections being provided with longitudinal projections, longitudinal rodsembedded in the base of said sections, inclined cross bars each my handand affixed my sea-i in the presence provided on each side with :Lpocket to reof the two subscribing Witnesses. ceive the projections ofsaid base and the ends of said rods, and means for removably 'GHASVAMARIEN' [L Si 5 securing said cross bars in said channel- Vitnesses: v

shaped rim. W. A. ALEXANDER,

In testimony whereof, I have hereunto set A ELIZABETH BAILEY.
